“He called me and as I turned round, his little face was there and at that moment, my heart exploded with all this love,” she said. “I thought to myself, whatever it is that we have to do, I love him so much, we will get through this somehow.

“It was just that moment, that feeling of oh my god, I love him so much, we’ll find some help, it will be OK. And I wish I’d told him that.

“He hopped on his bike and he cycled off, and he turned around and blew me a kiss goodbye, and that was the last time I saw him.”

Speaking through tears, she added: “I feel really grateful that I got my goodbye in a way, and I think that was my goodbye, you know?”
